From 5dd3f3071070f5a306bdf8d474c80062f5691cba Mon Sep 17 00:00:00 2001 From: Andreas Oberritter Date: Thu, 23 Oct 2008 12:11:19 -0300 Subject: V4L/DVB (9361): Dynamic DVB minor allocation Implement dynamic minor allocation for DVB, to allow more than four devices of the same type per adapter, based on drivers/usb/core/file.c. Add a new config option, DVB_DYNAMIC_MINORS, to make use of this feature, which defaults to no for backwards compatibility.
